[PATCH] create LC_MESSAGES directories and copy subversion.mo to the directories at compile time

Hi

I attach a patch to create LC_MESSAGES directories and
copy subversion.mo files to the directories and do some extra works.

[[[

* build/generator/gen_win.py
  (POFile.__init__) : set class member 'lang' to 'base'.

* build/generator/templates/build_locale.ezt
  () : change working directory by %~dp0 to make sure that the relative
        paths, which are used in the bat file, are correct.
  () : create mo directory only if the directory doesn't exist,
        to suppress a warning.
  () : create LC_MESSAGES directories if they don't exist.
  () : copy mo files to the LC_MESSAGES directories as subversion.mo files.
]]]

Regards.
